Overview
["The AQF-FF46 is one of Aqua Crest's most-purchased refrigerator filters, sold as a 3-pack for $25.10. It is certified to NSF 42, covering reduction of aesthetic impurities, which the certification specifically addresses as aesthetic impurities including chlorine taste and odor. Dimensions are 5.71 x 3.54 x 7.09 inches.", 'The review volume of 16,500 ratings at 4.6 stars is exceptional for an aftermarket filter. At that scale, the rating is one of the most reliable indicators of real-world performance in the category. Monthly sales of around 1,000 units confirm this is an actively purchased product. Per-filter cost in the 3-pack is approximately $8.37.', 'The certification scope is limited to NSF 42 for aesthetic impurities. No NSF 53 or NSF 401 is listed, and no capacity or filter-life figure is published. The product data also notes the material includes an air filter component, suggesting this may be a combo pack that includes both a water filter and a refrigerator air filter.']

Frequently asked questions
What is included in the AQF-FF46 pack?
The listing data indicates the AQF-FF46 may include an air filter component in addition to the water filter, based on the 'With Air Filter' material note. This suggests it could be a combo replacement covering both refrigerator water filtration and the internal air filter. Confirm what is included by checking the product listing or Aqua Crest's documentation before purchasing.
Why does the AQF-FF46 have so many reviews?
High review counts for aftermarket refrigerator filters typically come from being compatible with popular refrigerator models that have large install bases, combined with competitive pricing that drives high purchase volume. Over time, a well-fitting, affordable filter accumulates reviews steadily. The AQF-FF46's over 16,500 reviews reflect a combination of widespread compatibility and consistent buyer satisfaction.
Does this filter reduce lead or other health-effect contaminants?
Based on available data, the AQF-FF46 carries NSF 42 certification only, which covers aesthetic impurities such as chlorine taste and odor. There is no NSF 53 certification listed, which is the standard that specifically addresses lead and other health-effect contaminants. If lead reduction is a priority for your household, choose a filter with an explicit NSF 53 certification for lead.
